High latitudes may be particularly sensitive to climate change, however, adequate baselines for these lakes often lacking. In this study, we couple monitoring, remote sensing, modeling techniques generate baseline datasets temperature ice cover Arctic. No detectable trends were observed during study period, but a number interesting patterns noted among between regions. The largest Arctic was relatively unresponsive air temperature, while very responsive likely because it is fed by glacial runoff. Mean late summer water temperatures higher than differences ranging from 1.7 5.4°C 2.4 3.2°C lakes. warmest mean both regions 2004, exception glacially that highest 2005. Ice-out timing had high coherence within years, typically occurring May early-July Ice-on more dependent on size depth, varying region. Such analyses provide an important at time when there increasing interest high-latitude resources uncertain future.
